Millikan’s measurement of Planck’s constant

  • Allan Franklin


Robert Millikan is famous for measuring the charge of the electron. His result was better than any previous measurement and his method established that there was a fundamental unit of charge, or charge quantization. He is less well-known for his measurement of Planck’s constant, although, as discussed below, he is often mistakenly given credit for providing significant evidence in support of Einstein’s photon theory of light.1 His Nobel Prize citation was “for his work on the elementary electric charge of electricity and the photoelectric effect,” an indication of the significance of his work on the photoelectric effect.
